Evaluation of sapropel from lakes in Karelia and its influence on soil nematode fauna and crop growth and production (potato and perennial grass) was made. It was established that sapropel contained large amounts of Pb, Co, Mn led to the increasing in the number of parasitic nematodes, particularly specialized potato pest, cyst-forming nematode Globodera rostochiensis Woll. The first inputting of sapropel stimulated crop growth and productivity; in the second year in variant with contaminated sapropel values of these parameters were less than in control. Results showed that the using of sapropel as biofertilizer needs to define the possible risks of its application for soil biota and crops. Such kind of research has been first made and possesses novelty.
